Trying to change turn signal switch

Technically, a special puller was used. You could make one that uses the 3 retainer holes like the factory tool. First, make sure the snap ring under the switch has been removed. You risk damaging something prying on the upper section. If it's been off before you might be able to wiggle it off.

The bearing is an interferance fit on the shaft. It's loose in the rubber insulator inside the housing.
